Empty POST body

Hello i’m using Fetch on Node with React and Browserify, i trigger this code from a form submit:

event.preventDefault();

var form = new FormData();
form.append('a', 1);

fetch('http://localhost:8080/login', {
      method: 'POST',
      body: form
})

Can’t figure out why the request sent to the server has empty body, no matter what i put in (i also tried strings as body).

Any ideas?

Thanks guys, saved me a day. Essentially, what did work out for me: Client: fetching with headers: { "Content-Type": "application/json" } Server: adding app.use(require("body-parser").json())

I had the same problem. I solved using:

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
